The Sika occurrence is located 13 kilometres north of the Akie River about 191 kilometres southwest of Fort Nelson. The Akie deposit (094F 031) is 13 kilometres to the southwest.

The Sika showing area is underlain by folded and faulted Paleozoic platformal carbonates and basinal sediments. The western portion of the area is underlain by a synclinally folded sequence of Cambrian to Ordovician Kechika Group carbonates and Ordovician to Devonian Road River Group shale and siltstone. This sequence is overthrust, to the east, onto a narrow panel of Road River Group shale, siltstone and quartzite. This panel is in turn overthrust onto a synclinally folded, conformable package of Ordovician to Devonian Road River Group shale and siltstone and Devonian to Mississippian Earn Group shale and argillite. Barite mineralization occurs within the Road River Group turbidites and within the Upper Devonian shales of the Earn Group (Gunsteel Formation).

A grey barite bed, one metre thick, occurs at the top of a 110-metre thick quartzite-siltstone turbidite unit of Upper Ordovician to Lower Silurian age (middle Road River Group). The barite horizon is present at several localities and may have a possible strike length of 7 kilometres. Upper Devonian Gunsteel Formation shales (lower Earn Group) host nodular to almost massive barite and a 30-centimetre thick massive pyrite horizon.

In 1980, Cominco Ltd. conducted preliminary silt, soil and rock sampling, geological mapping and prospecting on the Akie-Sika group. In 1981, Cominco collected 1231 soil and silt samples using topographic and grid control, and continued the mapping at a scale of 1:10,000 over areas accessible by foot.

In 2007, Mantle Resources Inc. conducted exploration on the land formerly covered by Cominco and areas north and south covered by the Kwadacha claims group (owned by Ecstall Mining), the Sika and Akie-Sika claims (owned by Megastar Development Corporation), and the Bank claims group (owned by Mantle Resources Inc.). Exploration by operator Mantle Resources consisted of prospecting, preliminary mapping, soil sampling (585 samples), rock sampling (36 samples) and a gravity survey carried out over 7 kilometres. Soil sampling lines from the 2007 exploration program crossed historic lines and extended the spatial range of geochemical data. Soil surveys revealed several areas of strongly anomalous zinc values ranging up to 0.78 per cent but with comparatively flat lead values (Assessment Report 29846). The gravity survey was not as useful as hoped for. Rock samples from the area yielded up to 0.175 per cent zinc and 0.090 per cent barium (Osmani, I.A., Wilkins, A.
